36 Trillion-Shaped Engagement Rings for Modern Brides

So standout.

There are certain stone shapes that instantly come to mind when dreaming about an engagement ring—emerald, oval, cushion, pear, round, and princess cuts are all-time favorites from platinum and yellow-gold settings to contemporary takes set in rose gold or a mix of metals. Then there are more uniquely shaped engagement rings which have become increasingly popular with modern brides from colored stones to hexagon shapes and east-west settings. If you’re the type to feel drawn to the latter, trillion-shaped stones are a stunning and unique style of engagement ring to consider.

You may be more familiar with trillion-shaped stones as accents to more popular cuts like emerald or square diamonds and gemstones, but the triangular shape—which, fun fact, was originally created in the Netherlands—is beyond striking as the main event whether as a solitaire or multi-stone ring. You’ll find the three-sided stone available with round or pointed edges (aka curved or uncurved) and available in a range of unique settings whether you’re drawn to a two-stone ring, a double band, an off-kilter mounting, or halo accent.

As with a pear-shaped stone, a trillion-cut stone tends to look larger than it really is due to its shallower cut—if you’re the type of gal who’s set on a sizable diamond or gemstone (no shame in the game) but may not have the budget to spend on three or four (for five) carats, a trillion ring is a great way to go. In terms of sparkle, a shallow diamond does typically result in less brilliance which means a trillion cut may not be the most glittery ring in the bunch, but it will certainly sparkle and shine on your finger.

If you’re a price-conscious shopper, a trillion-cut gemstone or smaller diamond is a great alternative that still feels incredibly special and modern. As the stone shape continues to trend, more and more designers are offering dainty styles from sleek and minimal to those accented by a couple of tiny side stones. These restrained versions are likewise perfect for the low-key bride whose all about subtlety but still wants a stylish engagement ring.

From pared-back and dainty to glitzy and glamorous, ahead, peruse our edit of 36 trillion-shaped engagement rings for modern tastes.
